There are some rogue os in the Constellation Games acknowledgements. "N. K. Jemison" should refer to the Nebula and Hugo-nominated author N. K. Jemisin, not to a person who doesn't exist. And "Beth Lermon" is of course my friend Beth Lerman.

Surely these are far from the only typos in the book [I originally wrote "on the book"], but they're really bad, and deserve a special correction, and my apologies.
